Mycotoxins are secondary metabolites produced by fungi toxic for humans and animals. Due to their toxicity, the legislations of almost all the countries have limited the concentration of most important mycotoxins in food and feed commodities. The awareness that different chemicals, largely used in agriculture to control pests, could present both environmental problems and health hazard, led to large limitation of their use. Since 2014 European Community has banned about 50% of chemicals used in agriculture. In plant production systems chemicals were also the main tool used against fungal pathogens and against the contamination of food/feed by mycotoxins. Today the EC incourage the research to investigate for control and/or detoxification strategies using more environmental friendly “green” approaches and eco-compatible tools. Prefered methods for controlling mycotoxins contamination are largely preventive and use of biocontrol agents is one of the strategies. Different mushroom metabolites showed the potential to become a control agent for fungal growth and mycotoxin production. Particularly the exo-polysaccharides from medicinal mushroom Trametes versicolor, an edible and nontoxic basidiomycete, showed some interesting potential in mycotoxin control. Biocontrol agents from T. versicolor, such as polysaccharide Tramesan®, oligosaccharides from its partial hydrolysis and protein fractions, are proposed to counteract the growth of some mycotoxigenic fungal species (Aspergillus flavus, A. carbonarius, A. ochraceus), and the mycotoxins synthesis (aflatoxin B1, AF ; ochratoxin A, OTA). The inhibiting effect on germination, fungal growth and toxin synthesis of these compounds was evaluated. Furthermore, some aspects of their mechanism of action is proposed and discussed. Results indicated that biocontrol agents from T. versicolor could be a new more eco-compatible tools for the control of biosynthesis of several mycotoxins in food and feed chain. |
